First aid is a series of simple, life-saving medical procedures that a layman can be trained to perform in medical emergency situations, before the intervention of emergency medical technicians or doctors. It is best to obtain training in first aid before a medical emergency occurs. Supplies useful in giving first aid are often kept together in a first aid kit.
Training in first aid is often available through community organizations such as the American Red Cross or the American Heart Association. First aid instruction is a part of military basic training and the Scouting movement. In many British Commonwealth countries the Order of St. John provides first aid training and operates Ambulance services.
